The results showed that CD200, CD80 and TNFRSF14 were the highest in tumor tissues, CD274 (PDL1), CD86, LGALS9, NECTIN2, PDL2, PVR were lower than those in adjacent tissues but higher than those in normal tissues, and FGL1 was the lowest in tumor tissues. This evidence concerns the gene PDCD1LG2 and neoplasm.
